The city tower of Innsbruck is 51 meters high and is one of the most important landmarks in the old town of Innsbruck. It was added to the Old Town Hall between 1442 and 1450. It was the seat of the city's administration for centuries, and it had guards whose job it was to warn the residents in time from fires and other hazards. Tourists visit it to learn about its history and to climb to the observation deck at a height of 31 meters, where they can enjoy a wonderful view of the Tyrolean capital.
